ing in section; Fig. 2 is a perspectiveviewv ll of the preferred form of my invention; and

Fig. 3 is a perspectve'view ofa modified form of 4my invention.'

' This yinvention relates to Washers `and particularlyto the type of washer shown in my prior United States Patent N o. 759,599, dated 'lhe object oi my present invention. is to provide a comparatively thin malleable' iron washer which is so constructed that water can knotoollect between the underneath side of the Washerand the object upon which the washer rests or With which it contacts.

Another object of my invention is to pro-v vide a novel form. of Washer which can be easily converted int a nutvlock.

Referring to Figs. l and 2 of the drawings Which show the preferred form of my invention, i designates the baseol the Washer and f2 rnd 3 designate flanges on the upper' side of the base which are preferably circular or ring-shav ed, said ianges being arranged con centrical y so that they will be spaced away from eac'h other to form a channel 4. The underneath surface of the base 1 is perfectly iiat and is unbroken from the bolt opening 5 to the periphery of the base so that it Will be impossible for Water to collect between the ruiderneath side of the Washer and the object i upon which the Washer rests, the dangers 2- and S on the upper side oi the base forming a bearing surface for the nut 6 that is mounted. on the holt or rod 7 Which passesthrough the .vasher. The object'of forming the channel fi between the circular flanges 2 and S is to produce a Washer in \vhiclr .tfiie -material is of uniform thickness so th'iit it Will 'annealproperly andalso to eliminate surplus material that Would add to the Weight of the Washer.

A'Preferably the base 1 is provided on 'its upper side with tapered ribs 8 thatare-.'ermed' integral-with the iiang'e 2 to strengthens/me: and if desired the periphery ofv the base 'can be provided with integral projections 9 that can be forced into the object upon Whiohlthe Washer rests so as to prevent the Waaler from turning. l

In Fig. 3 I have shown a slightly .modified 'form `of my invention wherein the ring@ shaped flanges 24 'and 3a on the upper side of the base la are connected together by integral cross Webs 10 which impart additional arranged in alinementwith the ta ered ribs 8a. The 'flange 2a is also provided With Water that co ects inthe channe 4a to drain off andthese notches 11 also erform another function; namely, they ena le a cold chisel purpose of striking up a bur on the iiange 28L la can be provided at its periphery with projections, as shown in Fig. 2,' to prevent it from turning, or notches can be formed in the periphery otthe'base, as shown in Fig. 3', so

or other suitable tool to be inserted for thestrength tothe Washer, said cross Webs being notches or` openings 1l which' ermit any;

to prevent the'nut Jfrom turning. The base so v as to produce points l2 that caril be bent downwardly into engagement with the jb ject on which the Washer rests. Washer rests on or contacts with a metal ob- If the.

ject a bur can be struck up on the object so as to lie in one of the notches in the periphery ci the base and thus prevent the Washer from turning. Y

Having thus described my invention, what I claiinas new and desire to secure by Letters Patent is:

i. A Washer com rising a base. provided on its upper side with a plurality of substane tially continuous flanges that form a bearing surface for a nut, one of said flanges being arranged inside of the ot'. 4rs; substantially as described.

2. A Washer comprising a base provided on its upper side With a plurality of concenl tric ring-shaped dan es that form a. bearing .surface for a nut; substantially as described.

3. A Washer comprising a base rovided on its upper side with a plurality o concentric ring-sha ed flanges that are separated from each ot er toform a channel, the upper Aedges ofsaid langes forming a bearing sur face for a nut g vsubstantially as described.

'y in@ .4. A washer ccmprisin a base rovded un its upper side with e p urality o concentricely arrangedring-she` ed flanges, cross Webs formed integrally Witii said flanges, end strengthenjng'rbs formed integral With the bestaand the outer angegsubstantially as described. Y

5.2.1 Washer comprising' a bese having a net and unbroken 'underneath face, and a; plurality of concentrically arran ed lenges on the upper side of said base t at form 'a `beamingsurface for a nut, said flangesl being- 'separated from each other to form a channel;

snostantially as described. 1s-- 6'.. A Washer comprising a base havngfa int underneath face, and a, plurality ofcon- Fcentric :ring-shaped flanges on the upper side ofseid bese' to form a bearing surface for a @sense "underneath surface flat and unbroken, a plu-v relityv of concentric ring-shaped flanges on the upper side'of said base ada" ted to form a.A

bering' surface Jfor a, nut, sai flanges being spaced away from each other to forln e chennel, cross webs formed integral with sind' flanges, and notches or openings formed in .the outer flange; substantially as described.

In testimony whereof I hereunto aflix my signature inthe presence of two Witnesses, this ninth day of October 1907.
